Let's divide 86207931 by 612
We want to divide 86207931 by 612.

On to step 1:
If we divide 8 by 612, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 612

Advancing to step 2:
If we divide 86 by 612, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (2) from the dividend to 86 and continue with: 862 / 612

Moving on to step 3:
The number 612 fits into 862 1 times, leaving a remainder of 250.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 612 from 862 and we're left with 250.
Grab the next digit (0) from the dividend, add it to 250, then carry on: 2500 / 612

Step 4:
2500 divided by 612 is 4 with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 2448 from 2500 to get 52.
Bring next digit (7) of the dividend behind the 52 and repeat the process: 527 / 612

Let's proceed to step 5:
When dividing 527 by 612, we get 0 with a remainder of 527.
The next digit of our result is 0. 
Result so far: 140.0
If we take 0 away from 527, we end up with 527.
Bring next digit (9) of the dividend behind the 527 and repeat the process: 5279 / 612

Step 6:
The number 612 fits into 5279 8 times, leaving a remainder of 383.
Write down 8 as next digit of the result. 
Result so far: 1408.0
Subtract 4896 from 5279 to get 383.
Include the next digit (3) from the dividend after 383, then repeat: 3833 / 612

Moving on to step 7:
612 can be fit into 3833 6 times, resulting in a remainder of 161.
The number 6 becomes the next digit in our result. 
Result so far: 14086.0
Deduct 3672 from 3833 and we're left with 161.
Grab the next digit (1) from the dividend, add it to 161, then carry on: 1611 / 612

Let's proceed to step 8:
If we divide 1611 by 612, we get 2 and a remainder of 387.
Write down 2 as next digit of the result. 
Result so far: 140862.0
Subtracting 1224 from 1611 leaves us with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 9:
The number 612 fits into 3870 6 times, leaving a remainder of 198.
Record the quotient 6 as the next digit in the result. 
Result so far: 140862.6
If we subtract 3672 from 3870, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 10:
612 goes into 1980 3 times with a remainder of 144.
Use 3 as the next digit of our solution. 
Result so far: 140862.63
Deduct 1836 from 1980 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 11:
1440 divided by 612 is 2 with a remainder of 216.
Use 2 as the next digit of our solution. 
Result so far: 140862.632
Deduct 1224 from 1440 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 12:
If we divide 2160 by 612, we get 3 and a remainder of 324.
Put 3 as the next digit of the answer. 
Result so far: 140862.6323
Subtracting 1836 from 2160 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 13:
612 can be fit into 3240 5 times, resulting in a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 140862.63235
If we take 3060 away from 3240, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 14:
612 goes into 1800 2 times with a remainder of 576.
Write down 2 as next digit of the result. 
Result so far: 140862.632352
Subtract 1224 from 1800 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 15:
5760 divided by 612 is 9 with a remainder of 252.
Put 9 as the next digit of the answer. 
Result so far: 140862.6323529
The remainder is 252 after subtracting 5508 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 16:
The number 612 fits into 2520 4 times, leaving a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 140862.63235294
Deduct 2448 from 2520 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 140862.63235294 and a remainder of 7.2e-08.
